是role =" main"必要的< main>元件？ [英] Is role="main" necessary on a <main> element?

问题描述

如果定义内容主要部分的最具语义和可访问性的方式是标准< main> 元素，则使用ARIA地标似乎是多余的。是否真的需要将 role =main添加到元素中？

It seems redundant to use an ARIA landmark if the most semantic and accessible way to define the main section of your content is the standard <main> element. Is adding role="main" to the element really necessary?

推荐答案

并非所有现代浏览器都已将aria-role main 映射到< main> 元素（目前为止） Firefox 21+和Chrome 26+已映射它）。当所有浏览器都支持此功能时，属性 role =main可能会被删除，但同时最好继续使用它。

Not all modern browsers have already mapped the aria-role main to the <main> element (so far only Firefox 21+ and Chrome 26+ have mapped it). When all browser will support this feature, then the attribute role="main" could be dropped, but in the meanwhile it's better to still use it.
